Betty White is an inspiration. She turned 91 yesterday (17th Jan), and doesn't believe in retirement. She has been active in television and movies since 1939 (that's over seven decades) and is still going strong, plus she got a boa constrictor for her Birthday. What more could a woman beyond octogenarian-ism want? 

She currently presents her own show 'Betty White's Off Their Rockers' and still appears in the comedy series 'Hot in Cleveland'. She's had two shows named after her, both called The Betty White Show, the first in 1954, and another in 1979, the first a talk show and the latter a sitcom. However, she's best known now for her role in The Golden Girls, which ran from 1985-92 playing a 'naïve senior citizen' named Rose. 

Her infectious good humour seems to have kept her young. Last year she spoke to the Huffington Post about what it meant to be 90, she told them: "I'm having the time of my life and the fact that I'm still working -- how lucky can you get? I'm 90 years old and able to do what I do. That's a privilege." 

She's also a huge ambassador for animal charities and she she the most exciting thing about her visit to the White House wasn't meeting the president, but meeting his dog: "the big thrill was being with Bo, their dog. He's the cutest guy you've ever seen in your life. I spent a half-hour with him on my lap." 

So those are her tips, keep working and enjoy time with dogs. We'll take the latter.
